Emil Otto is introducing four new biodegradable solar panel cleaners, designated EO-SMC-001 to EO-SMC-004. These products, formulated specifically for cleaning solar modules, will debut at Intersolar 2024 in Munich.
EO-SMC-001 Modules Cleaner
Emil Otto—a German flux and cleaning specialist—is expanding its portfolio of cleaning chemicals for the solar sector with four new solutions, which will be presented to trade visitors for the first time at Intersolar 2024 in Munich. All four products have been designed specifically to clean solar panels.
EO-SMC-001 is a VOC-free, moderately alkaline cleaning product with a slight odor. This water-based, biodegradable solution is ready for immediate use and can be applied both manually and automatically. Its exceptional wetting capabilities make it ideal for spraying, brushing, and other automated cleaning systems.
Its alkaline composition effectively eliminates acidic and saline dirt without leaving behind greasy residues or impurities that could diminish the solar module’s performance. As a water-based product, EO-SMC-001 is not considered hazardous.
Other Solar Panel Cleaners
Emil Otto developed these new cleaners in response to the significant demand for specialized agents observed at Intersolar 2023. Markus Geßner, head of marketing and sales, noted that the new solar module cleaners, EO-SMC-001 to -004, share similar formulations and applications.

“Our engagement at Intersolar 2023 demonstrated that there is considerable demand for specific cleaning products in this field. As a result, we decided to develop new items for the next Intersolar and present them in Munich,” Geßner explained.
The product line also includes the mildly acidic EO-SMC-002 and the pH-neutral EO-SMC-003. Both offer cleaning results and application properties comparable to EO-SMC-001. With its neutral formulation, EO-SMC-003 is particularly gentle on sensitive materials and effectively removes soiling and deposits such as dust, pollen, or road grime.
Rounding out the product line is EO-SMC-004, a water-based cleaning agent designed to remove lichens, mosses, algae, and some molds. This cleaner uses an active oxygen formulation and is also effective at eliminating acidic and saline dirt.
Need for Solar Panel Cleaners
Because weather and air pollution impact photovoltaic systems, regular professional cleaning is crucial for maximizing solar power efficiency and maintaining high electricity yields. Proper techniques are also essential for safety, particularly when dealing with heavy soiling and steep panel angles.
Cleaning frequency varies by environment; agricultural areas may require two to four cleanings a year, while less polluted locations might only need it annually or biennially. Professional high-pressure equipment can efficiently clean up to 1,500 square meters per day, boosting green electricity generation.
Photovoltaic systems are exposed to various weather conditions and contaminants, from snow and rain to soot and bird droppings. This accumulated dirt can decrease electricity yield by up to 30%, underscoring the importance of regular cleaning for both performance and aesthetics.
Environmental compatibility was a key priority for these new cleaning agents, ensuring they are safe for use near meadows and green areas. Containing no flammable or corrosive additives, the agents can be rinsed off with water without harming flora or fauna. “We prioritised environmental compatibility because many solar panels are located in meadows or lush regions. As a result, all new cleaning products can be used in these settings without issue,” Geßner stated.
Emil Otto’s unveiling of biodegradable solar panel cleaners at Intersolar 2024 in Munich addresses the rising demand for specialized cleaning agents in the solar industry. With products tailored to various needs and environmental concerns, the company helps ensure maximum electricity yield and operational safety for solar installations globally.
